There's a market for both. I'm convinced we will see a 1/2-ton diesel from Toyota, if only because every other 1/2-ton maker will be offering one shortly.

Toyota introduced an all-new 4.5L V8 diesel in Australia earlier this year on the Land Cruiser 78. You can bet this will be the basis for the 1/2-ton diesel Tundra. It is probably too small for a HD Tundra, but for a 1/2-ton model it would be perfect.
